JOSEPH 'II-IIBADEAU, OF SAN-FRANCISCO, CALIFORNIA.

MOLD.

To all whom it may concern:

Be it known that I, JOSEPH THIBADEAU, citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements in Molds,of which the following is a specification.

This invention relates to improvements in molds and more particularly toa device of this character particularly adapted for use in constructingor finishing cornice molding.

The primary object of the invention contemplates the provision of meansin the nature of a specially devised mold support or frame, between. thebrackets or uprights of which a mold board or block is clamped at anangle to the cornice acted upon, this arrangement of the board withrespect to the cornice permitting the latter to be entirely made bysimply sliding or running the said device thereover.

A further object of the invention contemplates the provision of meansincluding a substantially triangular frame or support upon which themold block is diagonally clamped, thereby permitting the cornice actedupon to be molded or shaped, the re moval of the device beingunnecessary at corners for the reason that the miters or corners arecompletely and properly made from' one and the same operation as thecornice itself, thereby avoiding the necessity of using independenttools or devices as heretofore.

The invention still further resides in the provision of a simple andeflicient cornice mold wherein the several embodiments comprising thesame are so arranged as to permit mold boards of various size and shapeto be detachably clamped thereupon.

I The above and additional objects are accomplished by such means as areillustrated in their preferred embodiment in the accompanying drawings,described in the following specification and then more particularlypointed out in the claims which are appended hereto and form a part ofthis application.

In describing my invention in detail reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a detail perspective view illustrating the application of theinvention;

Specification of Letters Eatent.

Application filed July 23, 1913.

Patented Mar. 31, 1914.

Serial No. 780,784.

Fig. 2 is a top plan view of the device; Fig. 3 is a front elevation;and Fig. 4 is a side elevation of the device.

Before proceeding with the description of the drawings, I desire to callparticular attention to the fact that while I have evolved my inventionwith particular reference to ts application in connection with themoldmg of corni-ces, the same may be readily utilized for panel or othersimilar work.

Referring now to the drawings, wherein is illustrated the preferred formof my invention the numeral 1 designates a substantially triangularframe or support upon which the device comprising my invention isarranged, the said support, when in use, being slid or forced along theeaves or base of the cornice acted upon for molding or shaping thecornice itself. A pair of sub stantially L-shaped brackets 2 arearranged in spaced relation upon the frame 1 near the forward edgethereof, the upright portions of the brackets being braced or supportedin rigid relation to each other through the medium of brace rods 3depending at an angle from the top thereof to the said frame 1, the rodsbeing secured as at 4 at both the top and bottom. Like brackets 5 arearranged upon the support 1 in alinement with the brackets 2 abovementioned, the upright port-ions of the said brackets 5 being braced bymeans of brace bars 6 extending from the top to the bottom thereof, thesaid bars being secured as at 7 to the top and bottom respectively ofthe brackets.

A mold board or block 8 of any suitable design is adapted to be placedbetween the upright portions of the brackets 2 and 5 so as to extend atan angle thereto or diagonally thereupon for a purpose to be hereinafterfully described. Thumb screws 9 and 10 are carried respectively of thebrackets 2 and 5 for the purposeof clamping the said board 8therebetween, the provision of the said screws 9 and 10 permittingboards of various thickness or size to be employed in connection withthe frame or support provided therefor when desired. Handles 11,composed of any suitable material, are disposed so as to embrace thebrace rods 3 of the frame, the provision of the handles permitting theentire device to be slid or forced over the cornice acted upon duringthe application or operation of the invention.

Having described fully the detail construction of the device, it nowremains to set forth a little more in detail the operation thereof.

During the molding of cement cornice work, it has heretofore beennecessary to shape or construct the mlters or corners of the: cornlce byhand, which is not only ex- 1 pensive but necessitates the employment ofa person skilled in the art. By theprovision of a molding deviceconstructed as above described, this objectionable feature is obviatedand the miters are properly shaped or constructed with one and the sameoperation as a cornice itself. After fastening the mold board betweenthe brackets 2 and 5 provided therefor the entire device is placed uponthe eaves or base of the cornice and the frame slid or forced throughoutthe length thereof, the mold board 8 being disposed at an angle to thesaid frame or support permitting the latter to not only shape and moldthe cornice properly but effectually and properly mold the mitersthereof, the position of the mold board with respect to the frame beingclearly shown 111 Figs. 1 and 2 of the drawings. The device is firstforced along one edge or portion ofthe cornice until the edge of themold board 8 fits into the corner or miter of the cornice acted upon,whereupon the continued sliding of the device in the opposite direc-"tion will cause the cornice itself as well as themiters to be shaped ormolded into ll upon the brace rods 3, the former are positioned withrespect to the device in the manner desired.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referred to in the above description, asthe preferred embodiment, is the most efiicient and practical; yetrealize ing that the conditions concurrent with the adoption of mydevice will necessarily vary,

I desire to emphasize the fact that various minor changes in details ofconstruction, proportion and arrangement of parts may be resorted to,when required, without sacrific- .ing any of the advantages of myinvention,

as defined in the appended claims.

Having-thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. In a cornice mold, a supporting frame, standards fixedly secured tosaid frame, said standards being arranged in pairs, the standards ofeach pair being disposed in widely spaced relation to provide for thearrange ment of mold boards varying in thickness therebetween, and meansadjustable. upon said standards to clamp said mold boards in rigidrelation to said standards, as and for the purpose set forth.

I 2. Ina cornice mold, an angular supporting frame, standards fixedlysecured to said frame, said standards being arranged in pairs, thestandards of each pair being dis-, posed in widely spaced relation toprovide for the arrangement of mold boards varying in thicknesstherebetween, and means including a plurality of thumb screws adjustableupon one of the standards of each pair, said screws being adapted forengagement with the mold board. acted upon to clamp the same against theother of the standards. and in rigid relation thereto, as and forthetpurpose set forth.v p

3. In aicornice mold, an angular supporting frame, a plurality of,substantially L- shaped brackets fixedly secured to said frame, the saidbrackets being arranged in pairs, the brackets of each pair beingdisposed in widely spaced relation to provide for the arrangement of themold boards varying inthickness ,therebetween, handlecarrylng brace rodsfor the said standards,

and means including a plurality of thumb screws'adpistable upon onestandard of each pair, the said thumb screws being adapted forengagement with the mold board acted upon to clamp the said mold boardagainst the other ofthe said standards, as and for theipurpose setforth. v

In testimony whereof I afiix my signature in presence of two witnesses.I H V f JOSEPH THIBADEAU. Witnesses: y
